Specification of Letters Patent.

Application filed February 27, 1913.

Patented July 2i, ieia.

Serial No. 750,952.

T 0 all whom it may concern Be it known that I, HIPPOLYT SAURnn, a citizen of the Republic of Switzerland, residing at Arbon, Switzerland, have invented new and useful Improvements in Jacquard- Card-Punching Machines; and I do hereby declare the following to be a; full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention has reference to improve ments in machines for punching holes in the pattern cards used for controlling the automatic frame-moving mechanism in acquard embroidery machines.

In one type of punching machine the perforations to be made in the cards are determined by means of drums, which are provided either with holes or with pins, according to a definite system. Each such machine has at least two drums, by one of which punches are selected for piercing in the card those holes by means of which the horizontal movements of the work-frame are subsequently caused in the embroidery machine, while the second drum selects punches which pierce the holes by means of which the vertical movements of the frame are produced. The manner in which this is done is disclosed in Letters Patent of the United States No. 1,055,393, dated March 11, 1913, where two such drums, furnished with pins, are shown, and in which is explained how, by adjustment of these drums, the holes can be variously punched in the jacquard card, and also how the work-frame of an embroidery machine can be operated with the aid of this card. It is necessary each time after perforating to return the drums to their zero position, that is, that position in which there are no drumpins (or holes) opposite the needles, and the present invention consists in improved mechanism for effecting this return. For this purpose each drum is rigidly connected with a heart-shaped cam, and means are provided which can be caused to eXert pres sure on the cam-track in a radial direction, whereby the drum is restored to its zero po-. sition.

Two preferred embodiments of my invention are illustrated in the accompanying drawings in whichltigure 1 is a side elevation, showing such parts of a punching machine as are necessary for a proper understanding of the present invention. Fig. 2 is a plan of Fig. 1. Fig. 3 is a detail sectional view, showing the drum-returning mechanism drawn on a larger scale. Fig. t is an elevation of the same mechanism viewed at a right angle to Fig. 3. Fig. 5 is a plan of another embodiment ofthe invention, and Fig. 6 is an elevation thereof, drawn on a larger scale.

Referring to the first embodiment, as shown in Figs. 1 1, 1 and 1 are the two drums, both provided with holes 1 according to a definite system. The drums are rotatable independently, for instance in the manner described in Letters Patent of the United States No. 1,055,893, dated March 11, 1913, already above referred to. With each drum there is rigidly connected a heart-cam 2, 2 respectively, provided with a notch 2 lVhen the drumis in the zero position, the cam notch is uppermost, as shown in full lines in Fig. 3. Rigidly secured to the machine frame 3 is a bracket 10, forming a guide for the vertically reciprocal rod 41-. Atthe lower end of this rod there is mounted a roller 5, while the top end is furnished with a pin 11, which engages in the slot 12 at the extremity of a lever 6. Such rod and lever mechanism is provided above each heart-cam 2, 2 and both levers 6 are fixed on a shaft 7, which carries a lever 8 outside the frame 3 provided with a pin 9. 'lhis pin enters the groove of a cam 13, mounted on a shaft 14, which is driven continuously from any suitable source of power by means of a sprocket wheel 15 or the like.

When the two drums 1 1 have been adjusted, the one being for instance so set, that the heart-cam occupies the position shown in broken lines in Fig. 3, then on the pin 9, during rotation of the grooved cam 13, being received by the laterally deviating part 16 of the track, both levers 6 will be moved downward and the rollers 5 of the rods 4: will be pressed down upon the tracks of the heartcams 2 2 whereby the drums 1, 1 will be turned, until the rollers 5 enter the notches 2. When this occurs the drums will have been returned to the zero position again.

In the modification shown in Figs. 5 and 6, the mechanism is substantially the same as that above described, except that there is only one lever 6 mounted on the shaft'i. This lever is connected to a rod 4 which carries two rollers 5 at its lower end, each of which is located above one of the heart-cams 2 2 In this construction, therefore, both drums 1 1 can be turned to the zero position simultaneously by a singlelever.

Having thus described my invention, I claim as new- I i 1. In a jacquard cardpunching machine, a drum, means for rotatively setting the drum according to the manner in which the card is to-be punched, a cam rigidly connected with thedruni, and means for exerting pressure in a radial direction upon the track of the cam for the purpo-seof returning the drum to-the zero position.

2. In a jacquard card punching machine, a plurality of dru1ns,vn'1eans ifor rotatively setting the drumsaccording to the manner in whichthe card is to be punched, a cam rigidly connected with each drum, and means "-for exerting pressure in a radial directionuponthe-tracks of the cams for the purpose of returning the drums to the zero position.

-3. In a jacquard card punching machine, a plurality of drums, means for rotatively setting the drums accordingto the manner in which the card is to bepunched, a heart cam rigidly connected with each drum, and means for exerting pressure in a radial direction upon the track of the cams, for the purpose of returning the drums-to the zero position.

t. "In a jacquard card punching machine, a plurality of drums, means for rotatively setting the drums according to the manner in which the card is to be punched, a heartcam rigidly connected with each drum, lever mechanism adapted to exert pressure in a radial direction upon the tracks of the cams, and means vfor actuating the said mechanism, for the purpose of returning the drums to the zero position.

5. In a jacquard card punching machine, a plurality of drums, means for rotatively setting the drums according to the manner in which the card isto be punched,-a heartcam rigidly connected with each drum, a levercarrying two rollers, one locatedabove the trackof each cam, and means foractuating the said lever, whereby the rollersare pressed upon the cam tracks ina radial-direction, for the purpose of returning the drumsto the zero position.

-6. In a jacquard card .punchingm-achine, a plurality of drums, means for rotatively setting the drums according to the manner in which the card is to be punched, a cam rigidly connected with each drum,,-levers bearing on said cams, a rock shaft'on which the levers are carried, an independent cam, means toi-rotate the same continuously, an independentlever carried bysaid rock shaft and cooperating with the last named camwhereby upon each revolution of the latter the rockshaftis oscillated to pressthe-first named levers upon their respectivecamsin radialdirection for the purpose of returning the drums to the zero position.
